Embodiment Construction

[0018]In the following description, reference will be made to devices of which more than one are referenced in the drawings by a generic numeric descriptor N followed by a numeric suffix of the form N-1, N-2 . . . N-m. To the extent that reference is made to the devices without regard to a specific one thereof, such device(s) will be referenced by the generic numeric descriptor N only.

[0019]The present invention discloses an enhanced optical network (PON) processor adapted to serve a plurality of PON applications. The processor is a highly integrated communications processor that can operate in different PON modes including, but not limited to, a GPON, a BPON, an EPON, or any combination thereof. In an exemplary embodiment of the present invention the provided PON processor is fabricated on a single integrated circuit (IC).

[0020]Referring to FIG. 2, a non-limiting and exemplary diagram 200 of an enhanced PON processor disclosed in accordance with an embodiment of the present inventi...

Abstract

A method for processing data flows of a plurality of passive optical network (PON) operating modes, the method is performed by an optical network unit (ONU). The method comprises processing upstream data flows of said plurality of PON operating modes; and processing downstream data flows of the plurality of PON operating modes. The plurality of PON operating modes include at least a Gigabit PON (GPON) mode, a broadband PON (BPON) mode, and an Ethernet PON (EPON).

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a continuation application of a U.S. patent application Ser. No. 11 / 238,022 filed on Sep. 29, 2005. The contents are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates generally to communication using broadband passive optical networks (PONs), and more particularly to implementing PON processing on a single integrated circuit.BACKGROUND OF THE INVENTION[0003]As the demand from users for bandwidth is rapidly increasing, optical transmission systems, where subscriber traffic is transmitted using optical networks, is installed to serve this demand. These networks are typically referred to as fiber-to-the-curb (FTTC), fiber-to-the-building (FTTB), fiber-to-the-premise (FTTP), or fiber-to-the-home (FTTH). Each such network provides an access from a central office (CO) to a building, or a home, via optical fibers installed near or up to the subscribers' locations. As the transmi...
